Here I am running Ultima III and Ultima IV on my IBM PC/XT. Ultima IV starts at 14:30. The card is an old-style IBM CGA card. I know that Ultima IV supports EGA, but I am more interested in CGA composite color graphics. Because old-style CGA is being used, I used my Dazzle DVC-100 capture device because it can handle the "hot" composite video output signal.

CGA in composite video will often show "jailbars" in the form of repeating thin vertical black lines all across the image. While this is to some extent the nature of the signal, I have tried to mitigate the issue by boosting saturation and contrast on the capture card to the max while reducing brightness to a minimum.

The sound is from the PC speaker, recorded via the alligator-clip method. The audio in these games is based on pulse width modulation that bit-bangs on the PC speaker directly. As a result, the audio is fully speed sensitive and will sound increasingly higher pitched as your speed increases from the base 4.77Mhz 8088 CPU found in the IBM PC. No V20 or overclocking used here. I reuploaded this video because the previous attempt only put sound out on one speaker, but this video will output mono sound to both speakers. Thanks to NewRisingSun for showing me how to filter the audio to get rid of some nasty high frequencies.

There is no music except for the occasional theme played in Ultima III during combat, but there were no universal devices to play back audio other than the PC speaker until games began to support the Adlib Music Synthesizer Card and Roland MT-32 in 1988.

I have used the original floppy disk versions, these games do not come from the CD-compilations like The Ultima Collection. CD re-releases have been known to try to "fix" things that can break or distort the games when used on the hardware they were designed for.
